Is m^2 / (m-1) < m? 1). M > 0 2). M is not an integer Another approach: Rewriting the given equation - m^2/(m-1) - m < 0 => (m^2 - m^2 + m)/(m-1) < 0 m/(m-1) < 0, Thus there are two possibilities: m > 0 AND m-1<0 OR m >0 AND m<1, hence 0<m<1 OR m<0 AND m-1>0 OR m<0 AND m>1 NOT POSSIBLE. Hence, the ...

What is the remainder when K^4 is divided by 10? 1). K is not divisible by 5. 2). K is even. Stmt 1 - k can end in all digits 0 to 9 except, 0 and 5. If we look at the last digit of the k^4, when k does not end in 0 or 5, we find that it either ends in 1 or 6, depending if k is odd or even. Thus IN...

Is x an integer? 1). x^1/3 is an integer 2). x^1/2 is not an integer Stmt 1 => (X)^(1/3) = i where I = integer. Thus, x = i^3, which has to be an integer. SUFFICIENT. Stmt 2 => (x)^(1/2) = n where n = non integer, Thus x = n^2, if n = (13)^(1/2), then x = 13 hence x is an integer, however if n = (1...

If x and y are distinct integers, is x + y a prime number? (1) x and y are prime numbers. (2) x × y is odd. Stmt 1 - 5, 3. Thus 5+3 not prime. 2,3 2+3 prime. Thus INSUFFICIENT. Stmt 2 - x*y can be odd ONLY if x AND y are odd. And we know that odd + odd = even. If x and y are positive then x+y can ...
